OPERATION
Press and continue to hold down the trigger to
take temperature readings. The unit will take
temperature readings while the trigger is pressed
and held (SCAN appearing on the display indicates
measurements are being taken).
After the trigger is released, the last temperature
measured will be displayed for approximately 60
seconds, the display will then turn off automatically.
HOLD will appear on the display when the trigger
has been released to indicate that the unit is no
longer taking temperature measurements.
SELECTING UNITS OF MEASURE
Press and release the trigger to turn on the display.
Once the display is on (and the trigger has been
released), each press of the °C/°F button will
toggle between °C and °F. (If the trigger is being
held when the °C/°F button is pressed, this will
laser targeting on/off.)
LASER TARGETING
While pressing and holding the trigger, each press
the °C/°F button toggles laser targeting on and
off. With laser targeting on, each time the trigger is
pressed and held, the laser beam will be emitted.
CAUTION: Eye damage may result from direct
exposure to laser light.
DISTANCE SPOT/RATIO
There are other factors that may affect measurement
accuracy. The target must completely ll the spot
diameter seen by the infrared sensor; otherwise
readings will be inuenced by the surface
surrounding the target. The ratio of the distance to
the size of the spot being measured is 12:1. For
example, an object’s diameter of 100mm can be
measured from 1100mm.
BACKLIGHT
While pressing and holding the trigger, each press
the LOCK button toggles the LCD display backlight
on and off. With the backlight on, each time the
trigger is pressed and held, the LCD display will be
illuminated by the backlight.
VALUES RECORDED
With each press of the trigger, ve values are
recorded:
1. MAX - Highest temperature measured
2. MIN - Lowest temperature measured.
3. dIF - Difference between MAX and MIN
4. AVG - Time-weighted average temperature.
5. The value last displayed before releasing the
trigger. (Appears at the bottom of the display)
DISPLAY MODES
Each press of the MODE button will select one of
the 8 display modes. You can cycle through the
modes in this order:
“E” - Emissivity value display
(See the Emissivity section).
“MAX” (Maximum temperature) - press the MODE
button until MAX appears on the display. In the
MAX mode the highest temperature measurement
taken is displayed to the right of MAX. This value
will update each time a higher temperature is
measured.
“MIN” (Minimum temperature) - Press the MODE
button until MIN appears on the display. In MIN
mode, the lowest temperature measurement taken
is displayed to the right of MIN. This value will
update each time a new lower temperature is
measured.
“dIF“ (Temperature differential between MAX and
MIN) - Press the MODE button until dIF appears
on the display. The difference between the MAX
and MIN reading is displayed to the right of dIF.
This value is updated as new MAX and MIN
temperatures are measured.
“AVG” (Calculated {time weighted} average
temperature)- Press the MODE button until AVG
appears on the display. The time weighted average
temperature reading is displayed to the right of
AVG. This value is updated continuously while
the trigger is being pressed.
The term “time”, in reference to the averaging
mode, means all temperature measurements
are averaged together from the rst press of
the trigger. Example: If the temperature was
72° for one minute, then 20° for 1/2 second, no
signicant change in average temperature would
be displayed.
“HAL” (High Temperature Alarm) - Press the
MODE button until HAL appears on the display.
The high temperature alarm value that has been
set is displayed to the left of HAL. (See High/
Low Alarms section)
“LAL” (Low Temperature Alarm) - Press the
MODE button until LAL appears on the display.
The low temperature alarm value that has been set
is displayed to the left of LAL. (See High/Low
Alarms section)
“PRB” (Probe Temperature) - Press the MODE
button until PRB appears on the display. The
external probe temperature is displayed to the left
of PRB. If no probe is connected, noP will
appear to the right of PRB.
With a probe connected, the unit will display the
probe temperature without pressing the trigger.
While in PRB mode, the unit will turn off automatically after 12 minutes if no buttons are pressed.
Only Type-K thermocouple probes may be used
with this unit.
NOTE: The last mode selected will remain selected
the next time the trigger is pressed.
MEMORY RECALL
With each press of the trigger, ve values are
recorded:
1. MAX - Highest temperature measured
2. MIN - Lowest temperature measured.
3. dIF - Difference between MAX and MIN
4. AVG - Time-weighted average temperature.
5. The value last displayed before releasing the
trigger.
To cycle through each of the values recorded
during the last measurement, press the MODE
button. (See the “Display Modes” section for an
explanation of the values displayed)
HI/LOW ALARMS
An audible alarm will sound at both an upper and
a lower temperature limit. To adjust the alarm
temperature set points:
1. Press the MODE button until “HAL” (High
Temperature Alarm) or “LAL” (Low Temperature
Alarm) is displayed.
2. To adjust the temperature alarm set point, press
the or button. (Do not press the trigger while
adjusting the alarm set points). Press and hold to
advance the display rapidly.
3. Once the desired temperature alarm set point
appears on the display, press the trigger to conrm
the value.
While taking temperature measurements, an alarm
will sound when the temperature measured is
above or below High and Low alarm set points that
have been entered. If the temperature is above
the High Alarm set point, (((HI))) will appear at the
top right corner of the display. If the temperature is
below the Low Alarm set point, (((LO))) will appear
at the top right corner of the display.
The alarm will sound regardless of the Display
Mode if the temperature measured is above or
below High and Low alarm set points that have
been entered.
LOCK FUNCTION
The lock function allows the thermometer to take
measurements without having to press and hold the
trigger. When the lock function is activated, the unit
will take continuous temperature measurements for
60 minutes and will then turn off automatically to
preserve battery life.
To activate the lock mode, while in the E, MAX,
MIN, dIF, or AVG mode, press the LOCK
button. LOCK and SCAN will appear on the
display to indicate that the unit is in the lock mode
and is taking measurements. (Do not press and
hold the trigger while activating the lock mode.)
To de-activate the lock mode, while in the E, MAX,
MIN, dIF, or AVG mode, press the LOCK
button. HOLD will appear on the display to indicate
that the unit is no longer taking measurements. (Do
not press and hold the trigger while de-activating
the lock mode.)
EMISSIVITY
Emissivity adjustment is optional. Emissivity
adjustments are used to provide a truer
temperature reading. Different materials radiate
infrared energy at slightly different temperatures.
The emissivity adjustment is used to compensate
for different types of materials. The default emis-
sivity of 0.95 will cover 90% of typical applications.
The emissivity table provides a guide of different
emissivity values for different materials.
When the emissivity of an object is unknown use
a non-infrared thermometer, such as a thermometer with a surface probe to measure the object’s
surface temperature. Adjust the emissivity until
the temperature of the Infrared Thermometer
matches the temperature of the surface probe.
The emissivity value arrived at by this method
may be used to measure similar materials.

ALL OPERATIONAL DIFFICULTIES
f this thermometer does not function properly for
I
a
ny reason, replace the batteries with new high
quality batteries (see Battery Replacement sect
ion). Low battery power can occasionally cause
a
ny number of “apparent” operational difculties.
Replacing the batteries with new fresh batteries
will solve most difculties.
TTERY REPLACEMENT
BA
Erratic readings, faint readings, no display, or
a
ppearing on the display are all indications that the
b
atteries must be replaced. Open the battery com-
p
artment by sliding the battery cover in the direction
indicated by the arrow and then lift the battery cover.
Remove the exhausted batteries and replace them
with two (2) new AAA alkaline batteries. Make
certain to install the new batteries in the directions
indicated in the battery compartment. Close the
